Description

With film adhered method in the surface

The background of invention

1. technical field

The present invention relates to adhesive membrane is applied to lip-deep method.More particularly, the present invention relates to adhesive membrane is applied to lip-deep method, make the final profile of film and the surface topography below it closely fit.

2. description of related art

Adhesive membrane has many purposes in modern commerce.The huge image that for example will be used for advertisement and other public bulletin is printed on film, and by means of the pressure activation binding agent this film is sticked on wall and other surface.Terminology used here pressure activation binding agent comprises viscosity pressure sensitive adhesives commonly used and some binding agents (comprising the binding agent that can restore) like this, they may contain particle, tacky microspheres, littlely duplicate profile (microreplicated topographies) or such as this class bonding system, its caking property is caused by the pressure that puts between binding agent and the bonded matrix.

Because projection, depression and other out-of-flatness zone are contained in many surfaces that viscosity image film will be pasted, fit easily this surface or use thermoplastic film of advantageously used film is by means of heating its this surface of can fitting.The common way of settling this type of material is at first properly carefully this thin layer to be pressed into the smooth layer that the surface go up to form does not have fold, subsequently by means of for example cushion or brush pressurization and including air place acanthopore to carry out more local lamination process.To thermoplastic film, make film adheredly in the surface exerting pressure by means of for example cushion and the so flexible instrument of brush, help better applying at surface irregularity regioselectivity ground heating film.Common way also is, at separated region, the regional acanthopore of bubble for example arranged, so that discharge the air of being captured, applies force to separated region simultaneously, fitted and bonding in this zone.United States Patent (USP) 6,311,399 have disclosed a kind of hole that can produce to discharge the useful tool of air, and the pin that rebound performance is arranged has been installed here, it press to the film of institute's lamination and pierce through contain air section film so that the passage that can discharge institute's capture air to be provided.The air of capturing in the Disengagement zone also may be overflowed by the passage of tack coat inside.Such as by United States Patent (USP) 6,197,397 announcements, the Comply that can buy from 3M company ^TMPerformance Graphic Making Films bonding system includes the micro-structural passage that air that permission captures is overflowed in tack coat inside.

Although found various adhesive membranes, particularly the thermoplasticity adhesive membrane is in the coml extensive use, but the problem of waiting until be need be easier and faster method graphic films is fitted on the irregular matrix, for example usually appear at the riveted joint member on semitrailer and the cargo card car body.Because the riveted joint member has a large amount of manufactured heads, they need take measures to fit to improve, and the speed of finishing these operations becomes and is even more important.It is a kind of with film adhered method in the out-of-flatness surface also having needs, and there is very little risk to the damage of film surface.Stick on a transparent protective film or add again one deck image film can be for the pad pasting process and the surface when using subsequently the protection that provides to a certain degree is provided.Yet after using this sticking on, thicker rigidity is stronger thereby total membrane structure becomes, and this may make film more difficult in the applying at surface irregularity place.

When using cushion or brush pressurization makes it fit with the out-of-flatness surface to the thermal softening thermoplastic film, the danger of damaging film is higher.And the method for existing attaching film in the out-of-flatness surface usually has the requirement on the muscle power, and they not only require skill, also require high physical strength and patience.In addition, existing method has the requirement on the ergonomics, they usually require to use simultaneously a heating source and other several instrument, and for example an air releasing tool is so that form the air release aperture on film, also have one brush or a cushion to be exerted pressure film is contacted with the surface simultaneously.This being operated in such as having carried out just more difficulty under this environment on the limit that stand in semitrailer or other big surface.

The detailed description of better embodiment

Fig. 1 has described the typical substrates or the member of the adhesive membrane of usually applying ointment or plaster.This class A of geometric unitA may appear at such as on the truck bodies, and especially on lorry and the semitrailer body, the

flat board

12 and 14 of Jiao Dieing is an aluminium side flat board and parts 16 are vertical frame members of lorry body inside here.This member is fixed tightly in together by the rivet 10 that has ailhead 11, and ailhead 11 is given prominence on dull and stereotyped 12 outer surface.

With reference to figure 2, film 20 comprises backing and the active tack coat of pressure, and herein, tack coat is adjoining with dull and stereotyped 12 surface 23.In one embodiment, film 20 comprise the ability room temperature but under the rising temperature softening and thermoplasticity backing with stickiness.Have been found that normally used thermoplastic film material, for example plasticized pvc, polyolefin polymer and copolymer and various polyester all show the temperature range that is higher than its softening point that has pair method therefor of the present invention to be fit to.It should be understood that some softening point is that room temperature or the thin-film material that is lower than room temperature are applicable to that also the present invention does not have some application of heating steps.In addition, have been found that it all is useful in the present invention that plural layers for example comprise the film and the single thin film that add paste layer (overlaminate).Simultaneously, because many pressure reaction cements have thermoplastic properties, in heating embodiment of the present invention as a step of applying process, tack coat also can improve to the coating performance on surface.Suitable adhesive membrane can be buied from 3M company, is commonly referred to label film (markingfilm).Its example comprises available from being positioned at St.Paul, the 3M of the 3M company of MN ^TMScotchcal ^TMMarkingFilm and also available from the hot formed 3M of 3M company ^TMScotchlite ^TMReflective Sheeting.An advantage of the invention is that the membrane material that originally may and be not suitable for being used as the viscous layer press mold also can use now, because the machinery contact that has reduced makes heating to carry out in bigger scope in the applying process.

As an example, film 20 is manual being laminated on surface 23 and the manufactured head 11.As a result, the separating part 21 that is left the film 20 of flat board 12 by manufactured head 11 jack-up has formed separated region 24, and this phenomenon is called the support paulin.Similarly, if film 20 is laminated on the depression, the phenomenon of will putting up a bridge, at this moment film 20 has covered depression and has not fitted.Although film support paulin and put up a bridge and may not have big influence to being had also by the outward appearance of laminated thin film has adverse influence to the long-term durability of film.For example, if weather or other unfavorable conditions cause film 20 embrittlement or cracking take place, the part 21 that lacks support just may tear or be separated fully, then may be seldom as seen to the infringement of film 20 attachment portions, and this is to be supported by surface 23 because of it.

Although the present invention is useful on the surface to the relatively little film separating part of fitting, method of the present invention is not so limited.Have been found that by method of the present invention and use the technology of grasping easily, bigger film separating part also can fit on the surface.In one embodiment, film 20 is thermoplastic, and the separating part of close separated region periphery at first is heated softening and bleeds, and subsequently remaining separated region is repeated to heat and bleed.The volume of separated region diminishes gradually, until whole film separating part is fitted and bondd from the teeth outwards.Have been found that the technology that Gong to select for use, it is useful to the film separating part of fitting big, this technology is that the probe of will bleeding when not vacuumizing thrusts the separated region of film, begin then to vacuumize, and that part of film of the contiguous separated region of last heating, the probe farthest of bleeding begins and maintenance is simultaneously bled from leaving in heating.To the film that at room temperature can highly fit, may not need heating just can obtain acceptable applying.

With reference to figure 3, this figure has schematically described to realize the device of a kind of embodiment of the inventive method.This device comprises the thermal source 30 and the probe 32 of bleeding.Thermal source 30 can be, for example blows to the heated air source of film separating part 21, radiant heat source or any other thermal source, as long as film separating part 21 can be heated to suitable temperature and don't to film is burned, ignite or damaged by other.The energy of thermal source 30 can be from power supply, the burning of fuel or any other suitable energy.Preferable situation is the above temperature of softening point that film separating part 21 is heated to it, it better is such temperature, this moment is most of, better be whole residual stress all obtain discharging and don't as for heat to making film 20 lose its integralities, become by burned or be subjected to the damage of other form.

Refer again to Fig. 3, the probe 32 of bleeding comprises contact component 34 and attaching parts 36.Contact component 34 can be for example metal tube or hollow needle, and its end 33 is cut into a plane perpendicular to the centered cylinder axis of pipe as the crow flies.To be similar to the metal tube of 10 to No. 20 (gauge) hypodermic needles suitable especially for external diameter in having been found that.Such pipe can be from being positioned at 1001 West Saint Paul Avenue, Milwaukee, and the Aldrich Scientific of WI 53233 has bought.According to the explanation of Aldrich, the internal diameter of the hypodermic tube of No. 10 sizes is about 2.7 millimeters, and external diameter is about 3.4 millimeters.The internal diameter of the hypodermic tube of No. 20 sizes is about 0.58 millimeter, and external diameter is about 0.90 millimeter.

Best pipe number depends on Several Factors, comprises the airflow characteristic of quantity, level of vacuum and the vacuum source of thermal source type and temperature, film type, film thickness, diffusion barrier.Have been found that the 15-20 pipe is preferable to being used for the typical picture label film of rivet.Tend to lower the flow of probe than the pipe of minor diameter.In some cases, the flow of attenuating has adverse effect to the net pressure difference of film portion 21 being pressed to manufactured head 11 and surface 23.The flow that lowers has also lowered film portion 21 and has fitted in speed on manufactured head 11 and dull and stereotyped 12.On the other hand, larger-diameter pipe tends to form bigger perforation on film 20, and this may have adverse effect to outward appearance.Have been found that the special material that is used to make pipe be not strict with that although metal tube, especially the pipe of being made by the stainless steel hypodermic needle tube has durable advantage.Should understand, be suitable though have been found that cylindrical tube, and the pipe of other transverse cross-sectional shape also can use, and in some cases may be more beneficial so that become preferred.In addition, though have the advantage that constant cross section cylindrical tube has simplification, have in some cases that can to change the pipe that maybe can adjust the cross section size may be useful.For example, in order to strengthen air-flow and to lower the danger of stopping up, the short tube of the minor diameter that contacts with film may swell or substitute with larger-diameter pipe.Also have, different probe pinpoint shapes are applicable to different application scenarios.For example, flat tip is arranged, have been found that this class probe tip is applicable to the preceding just film of heating of bleeding with the probe pinpoint that cuts as the crow flies perpendicular to the plane of tubular axis line.On the other hand, probe advances under the situation of film with regard to puncture before heating, like have very big separated region to bleed or do not use that heating the time done like that, having probe sawtooth or analogous shape that has of cutting sth. askew may be more useful, the easier cutting film of this shape.Having imagined to provide many batches to have difform probe, they are dismounting and installation easily, so that to any special work, the user can select only probe, and if desired, can before the only probe of decision, try out various probe tips.

With reference to figure 4, the capture air of extracting out from separated region 24 begins like this, and the probe 32 of bleeding touches the separating part 21 of film, and it is continued to advance formation depression 40 to membrane portions 21.In one embodiment of the present invention, this downward propelling is that separating part 21 at film is heated and finishes after softening.In this process sometime, the downward propulsive force of thermoplastic and probe 32 has reached is enough to produce the degree that penetrates in film portion 21, so that as if has formed hole 50 depicted in figure 5 like that.A kind of embodiment is enough thermoplastic film portion 21 to be applied enough probe power just produced simply and penetrate, and in another embodiment, before thermoplastic, one predefined probe power is applied in advance and is remained unchanged, heat film portion 21 then to enough softening degrees, so that probe penetrates film portion 21 and forms hole 50 thereupon.Also also have a kind of embodiment, need not heat, the probe tip just can penetrate film portion 21, and according to the performance of used film 20 decision needs heating or not the needs heating just make film adhered in the surface.

The inventor do not wish to be subjected to about probe penetrate the thermal softening film really any particular theory of cutter reason fetter, in fact the observation to penetration phenomenon under the various conditions draws not only a kind of pattern that penetrates.As if in some cases, vacuumizing of probe makes the thermal softening film portion be drawn into probe, this has and helps penetrate.In other cases, probe may machine cuts leave at least a portion film before penetrating.Similarly, the definite character of sealing and unclear between the contact component 34 of probe 32 and the film portion 21.And, do not know whether tight sealing takes place, if perhaps take place, this sealing lasts long.As if yet the air-flow between contact component 34 and hole 50 is subjected to enough restrictions, enter probe 32 to allow enough pure qi (oxygen) stream from regional 24 outflows, and the air pressure of separated region 24 is lowered, and makes it be lower than environment or atmospheric pressure.As depicted in figure 6, this hypotension is effective to eliminating separated region 24 and being fitted in the surface.In some cases, as if can on film portion 21, make a hole with best instrument earlier, make vacuum probe really not enter this hole then, fit thereby in separated region 24, produce enough air-pressure drops and form near this hole.The present invention is not limited to lower any special hydrodynamics pattern of separated region internal air pressure process.

With reference to figure 7, after applying is finished, remove probe 32, stay hole 50, if the size of selected contact component 32 is suitably, this hole can be little of being not aware of basically.

The term vacuum source can comprise any such device, it preferably provides any container that can lower air pressure, be connected with vacuum source when bleeding at the probe of bleeding, it can produce air-flow is enough to make and reaches an efficient vacuum degree in the separated region 24.Vacuum source can be continuous or intermittence.The example in continous vacuum source comprises the piston-type vavuum pump, rotation aerofoil profile vavuum pump, as if be used for the Scroll-type vacuum equipment of vacuum cleaner, as if the hydrodynamics air-stream generating device of venturi apparatus, and other continuous flow instrument that when producing an effective current rate, can lower air pressure.The example of intermittent vacuum source comprises that spring drives or manual piston and deflector, elastic ball, and other produces the device of decompression with the expansion of a closed volume.The closed volume that vacuum tank and other a certain amount of air have been drawn out of also can be used as vacuum source.Vacuum source also can comprise the combination of said apparatus and instrument.

The terminology used here vacuum valve is meant any at the valve of bleeding and packing between probe and the vacuum source.Vacuum valve can be used for controlling vacuumizing the probe of bleeding.

In one embodiment of the invention, the probe 32 of bleeding is hand-hold device.More specifically, the close size of picture pencil or this writing implement of pen, shape and configuration are substantially preferably arranged, a benefit is so just arranged, make the people of this architectural device of many uses dexterously to use as the probe 32 of handheld probe.In the embodiment of using heating, electronic heating gun can be used for the heating of film.Because this class heating gun can have been bought on market with air themperature sensing device and air themperature control system, have been found that the operator can reach that high-caliber skill effectively heats and the operation of finding time with the applying that obtains film portion 21 around rivet and other surface irregularity zone and don't can big damage be arranged to film 20.An advantage of the invention is, because remove outside the drilling point, be heated film portion 21 and bleed and almost do not have what mechanics contact between the probe 32, in some cases, just may be in the applying process film portion 21 is heated to higher temperature and unlikelyly causes following this class damage, such as brush, cushion or similarly other device contingent damage when film 20 under the thermoplastic state contacts.This additional flexibility has alleviated the tired of operator and because film 20 higher softening degrees have improved applying.

In another alternative embodiment, as if schematic description that Fig. 8 did, use a kind of mechanical grip and Move tool to settle probe 32 and it is advanced to film separating part 21.For example by probe clamping device 80 probe 32 being placed in relative manufactured head 11 is on the same horizontal direction, figure middle probe clamping device 80 is cross section schematic diagrames, and it is placed on the film 20 and can slides thereon in the horizontal direction probe 32 is located.It is preceding its final position of bleeding along numeral 81 directions of arrow of mark mobile before fixing its position that Fig. 8 describes anchor clamps 80.

Fig. 9 has described probe 32 and has been positioned on the position that will bleed to film separating part 21, and this is with before film 20 contacts.Preferably, probe clamping device 80 will not be positioned to and contact with that part of of any thermal softening of film 20, because this may produce mechanical damage to film surface.Probe clamping device 80 can comprise the positioner such as groove or other member, they will be fit to the special machine feature of the matrix of film 20 lamination of wanting, and its objective is that rivet 10 or other member that clamping device 80 relative film separating parts 21 will be fitted position.For example, clamping device 80 can comprise one or several groove, and these grooves can be accepted and be positioned at other rivet that film 20 is not heated the zone, so that rivet 10 is done correct location relatively.In addition, some a part or whole part of clamping device 80 can be made by transparent material, so that can observe the zone of contiguous separated region 24 better.

Thermal source 30 is only schematically described, and it can have many forms, for example a hand-held hot rifle or a heater that is connected with probe clamping device 80.As selection, thermal source can be connected with probe and as a single handheld unit.An other selection is that handheld unit can comprise a self-contained vacuum source, for example a vavuum pump.

Figure 10 described just pierce through film 21 and begin to bleed before with the diffusion barrier 21 contacted probes 32 of bleeding.Probe 32 moves to pierce through film to the direction of arrow 91.Probe 32 vertical moves and can be produced and be controlled by any proper device to the propelling of diffusion barrier 21, and this device does not draw among the figure.This propulsion plant comprises the driver of hand-drive, fluid or vacuumizing, mechanical linkage, and such as motor and the such electro-mechanical devices of coil, and spring and other elastic mechanical element.

With reference to Figure 11, in an alternative embodiment, can equip a combination 142 of the probe 32 of bleeding.In this embodiment, combination 142 also can comprise a combination 140 of heating element heater 146.What should understand is, is element separately though heating element heater 146 is drawn as, and they can selected whole parts as single source.For example, they can be one group of nozzles on a single header that hot-air arranged.Thermal source 140 can be that air source, radiant heat source or other suitable thermal source are forced in heating.In the embodiment that Figure 12 describes, probe 32 preferably is positioned to and can moves independently and resilience, like this when combination 142 when dropping to film separating part 21, each probe 32 can both contact with film separating part 21 and can or not cause or hinder other probe and also touch film portion 21 with suitable power.With reference to Figure 13, one or more probes 32 may penetrate film 21.The probe that touches non-separated region film can not pierce through film, and estimates that those probes that touch separated region can pierce through film, as if the situation of being described in puncture site 164.

Embodiment

In the following embodiments, with of the applying of vision estimation thermoplasticity adhesive membrane to test panels, the applying degree that evaluation may take place in the applying process, what air was carried secretly avoids, fold do not exist and to other damage of film.With film adhered during in protrusion of surface place, of applying is useful to be measured is separately apart from (lifting distance) d, and it is meant from the burble point of prominence to the film separating part and the surperficial contacted distance that will be stuck.To not taking the situation of fitting fully of paulin, film sticks to the edge (for example edge of manufactured head) of prominence fully, and at this moment separately distance is 0.With reference to Figure 14, this figure has described film separating part 21 outer separate confinement 171 and interior separate confinement 173, here film 20 is glued to beyond border 171 on the surface 23 and is glued on the manufactured head 11 with interior on border 173, but separate in the zone 172 outside within the border 171 and border 173., for example record separately apart from d in several sampling points measurements apart from d ₁, d ₂, d ₃And d ₄Measured value d ₁-d ₄Mean value be used as average separately apart from D.Because divided thin film from effect be can be observable basically, so the position of border 171 and 173 can be with visual decision, can accomplish enough accurate the measurement with mm-scale usually.As a selection,, can select an exemplary position as single-measurement value d based on to the total visual effect of support paulin.Have been found that this is called visual average method and in many cases the degree on the film surface that fits to the rivet peripheral region has been provided one and reasonably describe.

Cause that another defective that film is not exclusively pasted is that air is captured, it is to bubble or the form of fold film appears near the prominence but contiguous with prominence place.Fold can be captured or deformation of thin membrane is caused by air, and they stay unnecessary film in specific place.It may not be nonvolatil that air is captured.If the air capacity of being captured is enough few, then air can be overflowed in time, makes this regional film be pasted on equably on the matrix and does not have because the such outward appearance of vision flaw that capture air causes.

Many technologies that the thermoplasticity adhesive membrane is fitted in the surface can produce film damage.This type of damage type has surface abrasion, cut usually, tears or acanthopore, and this produces by being applied to the instrument on the thermal softening film and its pressurization put in place.In addition, owing to causing burned, fold or damage, the superheated of film or other contingency also can take place.In the following embodiments, the damage of these types will lack as visible damage.An advantage of the invention is that the wearing and tearing, cut and other surface damage that are caused by the machinery contact have reduced, this is because film is finished by means of air pressure difference rather than machinery contact the pressurizing attaching of want adhesive surface.In some cases, the present invention may produce can observable hole, and they are from the puncture of the probe of bleeding.The diameter in these holes is millimeter (mm) levels.

The following example is selected for use can be from 3M company, St, the various thermoplasticity adhesive films that Paul MN buys, they are laminated on the aluminium matter breadboard that painted, the size of described plate is 10.2 * 30.4 centimetres, it is that 7.7 centimetres test rivet riveting is gone into that 4 spaces are arranged, 3.5 centimetres at the nearest rivet pitch breadboard edge of separating test panel edges.Rivet pitch is selected to such an extent that put rivet enough far away, to avoid causing influencing each other between them in lamination process.Breadboard uses that class standard white freight train paint that is generally used for semitrailer to paint.Used rivet is that class that is generally used for making aluminium matter semitrailer car body, and the diameter of its manufactured head is 12 millimeters, highly about 1.5 millimeters.Riveting is on breadboard tightly for the rivet quilt, and ailhead then closely is placed on the surface of painting.
